Electrical contact of electrical connector

Abstract

A plurality of contact are received within the corresponding passageways of the insulative housing of an electrical connector, respectively. Each contact has juxtaposed first body and second body angled with each other via a connecting section linked therebetween. A resilient contacting section extends upwardly from the first body. A spring arm extends upward from the first body and includes a wide plate section adjacent to the first body and a narrow bulged contacting section at a top thereof. During operation, the plate section is parallel to a top face of the housing in a compressed manner.

 a first body and a second body sideward spaced from and angled with each other and linked to each other via a connecting section; 
 a deflectable spring arm extending upwardly from an upper portion of the first body and including a wide plate section adjacent to the first body and a narrow bulged contacting section at a top end thereof; and 
 a horizontal soldering tail located at a bottom end of a blade which extends downwardly from a lower portion of the second body and is located below the connecting section; wherein 
 the first body and the second body are perpendicular to each other viewed along the vertical direction, and the spring arm extends perpendicular to the first body and parallel to the second body viewed along the vertical direction; wherein 
 a pair of barbed structures are respectively formed on lateral outer edges of the first body and the second body. 
 
     
     
       12. The electrical connector as claimed in  claim 11 , wherein the first body lying in a plane extending in a transverse direction perpendicular to the vertical direction, and the second body lying in another plane extending in a front-to-back direction perpendicular to both the vertical direction and the transverse direction. 
     
     
       13. The electrical connector as claimed in  claim 12 , wherein the passageways are arranged in rows along the transverse direction, and the passageway of the neighboring rows are offset from each other with a half pitch of the passageways in each row. 
     
     
       14. The electrical connector as claimed in  claim 11 , wherein a tapered transition section is formed between the plate section and the contacting section.
